Initialize Element Status with Range (E7h) 2
The Initialize Element Status with Range command allows the host to
request an inventory of a range of elements in the DX-Series system. The
DX-Series system conducts the inventory and determines if each element
within the range contains a tape cartridge. The inventory reads each
tape’s bar code (unless commanded not to).
The DX-Series system does not accept any other commands from the host
during the inventory process.
The host can issue an Abort of the inventory for the DX-Series system. If
another Initialize Element Status command is then issued, the inventory
process is restarted from the beginning.
The format for this command data block is shown in table 8.
